Politico reports that Arizona Republican Governor Jan Brewer has formally petitioned the United States Supreme Court to overturn the 9th Circuit’s opinion that important parts of the state’s tough immigration law (SB 1070) violate the U.S. Constitution.

Brewer said in May that she was “frustrated” by the court’s ruling and planned to appeal it.

“The bottom line is, is that everyone knows that the 9th Circuit has a reputation of being very, very liberal,” she said. “After deliberating and thinking about it, I said, ‘Let’s just go to the Supreme Court.’”

As usual, the outcome will probably hinge on the moderate views of Justice Anthony Kennedy.
